They had made their way, completely silent, to one of the statuary-filled clearings on the edge of the garden. An empty alcove in on low wall was surrounded by bushes, clearly meant to hold a statue or image of some kind. Celestia slowed, letting Twilight pass her, and then said the first words since they had left.
“Twilight... If what I do is too rough, please stop me.”

“Pr... Celestia, how could-”
She went to reply, but all opportunity left her as a pair of hooves pushed her up onto her hind legs and pinned her against the wall. She moaned into the sudden fierce kiss, completely engulfed and overpowered and loving every minute of it. Celestia was frantic above her, and she was just as needy herself, her hooves struggling to keep up with her mentor’s speed. Eventually they pulled apart, gasping huge lungfuls of air, staring into each other’s eyes.
“Nnnh. That... Was just right. Not too rough. I don’t think, anyway.”

“Good. So, where do you think we should go to get... sufficient privacy?”

A wicked thought came up in her mind, and if she had asked herself several months ago about the concept, would have gotten only blushes and stammering embarrassment as an answer. But now, it seemed both reasonable and appropriate.
“...Right here?”

Celestia stared, and then looked from side to side. Twilight followed her gaze to confirm- A long path going both ways, the thick trees of the central garden at her back, a wall behind Twilight. Bushes to either side of her, and an alcove precisely sized to fit a pony like herself.
“And what gave you that idea, my faithful student?”

“I, uhm, I don’t think I could make it back to our room. Or any room, really. I was just going to give up when I walked up to you in the ballroom.”

“Ahha. I... To be entirely frank, I think I could have held out longer... Had I used my magic. But it would have been an unfair advantage to use tricks that I know full-well you don’t have on your side. And so my sadly long-rested and already rather... strong, let’s say, libido won out.”

“You didn’t have to do that, you know. I would have accepted my defeat.”

“Mmyes, but I am not entirely sure I would have accepted it. Maybe, Twilight, I wanted to lose.”

With that, Celestia leaned into her again, and this time Twilight could try to respond in kind-- Her hooves wrapping around Celestia’s back, leaning against the wall to take the pressure off her hind legs. She felt heat and pressure at her lips and gasped, letting her lover’s tongue meet her own. It was an entirely different kind of intensity, and while she tried in vain to do the same in kind, her quaking desire just left her too frazzled. She would have to find the time to get better at that in the future-- For now, she wanted to make Celestia happy.

“I...”

Celestia broke away, looking down at her with a smile.
“Yes?”

She mumbled out a reply that even she couldn’t hear properly.

“I’m sorry, I didn’t quite hear you.”

“Princess!”

“What’s the matter, Twilight? I did concede after all- The least you could do now is tell me, firmly, what it is you want to say.”

She looked down at her chest and muttered again, and Celestia prodded her once more. Finally, she gave up and simply said it, plainly and clearly- Even knowing nopony could hear didn’t make it any easier.
“I want to... please you. Here. Now.”

Celestia leaned in to kiss her, just once, gently. When they pulled apart, her teacher turned away to face the treeline, her tail hovering just in front of Twilight’s face. She couldn’t help but stare, mesmerized by the colors, suddenly noticing the strong and sharp scent of arousal before her. It was... stronger than her own, or Applejack’s or Rarity’s. It was a beautiful scent, but one that was overwhelming her already. Without question, it was a mature mare in front of her... And she hoped she was ready to please her.

--------

Back against the wall, Celestia tried to relax. She succeeded, of course, but there was effort involved- Nopony had been that close behind her in... some time. She could practically feel Twilight’s gaze on her rump, and her tail began to twitch and flow in response. It would be entirely unbecoming of her to simply flip her tail up and reveal herself in an instant... So that’s precisely what she did. The lack of decorum was absolutely worth the gasp she heard, and a moment later she got to respond with her own gasp when a soft, tentative hoof pressed into her stifles, sliding up and down against her coat. Her perception narrowed, her focus on this moment- Nopony would be coming down this path, so there was no real need to pay attention to extraneous things like the outside world. Only Twilight, right now.

Celestia closed her eyes and completely let herself go, slumping forward slightly, legs dropping from their normal refined arch into the slouch of somepony exhausted after a day of work. Her tail was off to one side, flowing gently against the greenery, and her student... Her student was gently, carefully, slowly exploring her. It was agonizing, in all of the best ways, and if she had been sure it wouldn’t come off harsh, she would have told the mare to speed up. But... In a way, she deserved this cautious treatment, this slow-roll to her actual release. After all, she did concede... And thinking about what Twilight might do with her ‘prize’ led another shiver up her spine.

It wasn’t long before Twilight was finally making contact, occasionally murmuring something to herself as her hoof pressed against Celestia’s lips. She groaned and tried not to buck against the pressure. It was certainly not unfamiliar, but she was used to these hooves embracing her, or clapping in joy after a well-taught lesson. To feel them so intimately was entrancing, and the pressure only got stronger. Moments later Twilight was slipping inside, finally applying force where it was needed most, although... It was entirely unlike Celestia to leave a partner without reciprocation, but she couldn’t... Oh!

“Twilight...”

“Ah! Celestia, did... Did I do something wrong?”

“Absolutely not. It’s wonderful, I just... I hate to leave you out in the cold, so to speak.”

“Princess, it’s fine- I can wait my turn.”

“And what if I said you didn’t have to?”

Rather than wait for a response, she simply acted.

--------

Twilight was going to respond, but then her world went dark. Not dark, actually, but... Secluded. She was suddenly covered from head to haunch in a blanket of warmth and faint light- Celestia’s tail, already the size of her, was now draped across her entire body, shielding her from the sky. There had never been a point where she could honestly say she felt so... Embraced. Engulfed, shrouded, covered, wrapped up. Whatever word she tried to put to it seemed insufficient.
“Celestia, it’s... beautiful!”

“Funny, that: I haven’t even started.”

“Whu-“
She was interrupted by the sensation of faint stroking and tickling at the base of her tail. Dozens of individual sensations, touches and pokes and prods and strokes, all moving across her coat separately. Twilight had never even thought about a unicorn, or alicorn in this case, using their mane and tail like this. And when the gentle sensations got stronger, she got the message and got back to work, her hoof working slowly- Her teacher may be experienced, but that did not make her any less nervous about causing discomfort. Concentration was lost once again when the first few tendrils of hazy feelings reached beneath her tail, but she eventually went back with gusto. And when a single thin wave of pressure passed her lips and began to trace inwards, she held back a moan and leaned forward. Her entire body was surrounded in Celestia’s warmth, no sense in leaving her muzzle out.

--------

While Celestia had not actually used her prehensile control of tail and mane in quite some time, it was an easy method to get back into- Her tail sweeping across her student’s lovely body, transmitting every sensation as if it were her own hooves’ touch. Admittedly, she did nearly lose control when Twilight first began to lick, holding back a gasp and gently bucking her lover’s face. They worked out a rhythm, at that point- Twilight would lick and stroke in time with her thrusts and the ministration of her tail. Lost in the pleasure at that point, she almost didn’t notice somepony coming down the path. Emphasis on almost. A message was quickly sent towards her student, the two-way communication spell kicking back in.

Twilight, somepony is coming.

I know, Princess.

She groaned at the terrible pun, Twilight’s gleeful little laugh coming across even in telepathy.
No, I mean on the path. We need to stop.

Oh!

A pause. Longer than she had hoped for, with no sign of Twilight actually letting up.
...Can I have my prize for winning our wager? Now?

...You aren’t.

Celestia, as my reward, I would like permission to not stop. And I don’t want you to, either.

On the outside, she sighed, as if her student’s choice exasperated her. But on the inside, she was gleeful- She had hoped Twilight would have some leaning towards her own personal level of... shall we say, deviance? Receiving confirmation of this fact was absolutely worth the awkwardness or embarrassment of this next conversation.

Very well- I would hate to disrupt you when you’re in such a, -ooh-, groove.

They shared a laugh, followed by a bit of gasping between them, as Twilight huddled further under her tail and Celestia did her best to compose herself. At first, she did not recognize the unicorn walking towards her- And that alone was enough to confirm their identity.

“Mr. Finish! What a surprise to see you this evening.”

“Well hello there, madam. I had just been taking a break from the monthly Consortium of Night Shop owners-- Nickle’s still there, of course, but I needed the fresh air..”

Behind her, an extremely eager young mare was doing her best to make her squirm, shiver, or outright break. Celestia smiled, her concentration honed to a blade’s edge as she carried out the conversation as if nothing was wrong. No sir, nopony approaching a chain of delicious orgasms here.

“As did I. I will admit, I had not realized they were holding regular Consortiums again- How has it been?”

“About as boring as any other bureaucratic shindig, with the marginal bonus of everyb... everypony being involved in something weird. Or at least ‘adult’, if that’s the better word for it. Makes for good side conversations.”

“Mmh, I would imagine. I know I personally prefer spending time with the more... Unique merchants, when it comes to mmh meetings.”

If the shop-owner had noticed anything odd about her sudden groan, he said nothing of it. Instead, he began engaging her in small talk- Banal, entirely uncomplicated, easy to follow. At least, it would normally be easy to follow, save for the presence of an extremely eager tongue lapping at her insides, an equally-loving pair of lips tugging and pulling at her. A moment of iron concentration to keep her face straight (pay no attention to the mare behind the plothole), and she replied.

“I do apologize, but the event I am hosting has left quite a bit on my... mind. You were saying?”

“Ah, no worries- I was just askin’ if you were planning to make visits to the shop regularly- We can accommodate planned visits, if you’re interested in special orders ‘n such.”

“Well, I do believe I will have to ask a certain somepony about that- It would be nng silly of me to go without them, after today.”

“Ah, so it is true that you’re teachin’ the girl more horn tech than just magic, wink wink?”

She would have responded with some kind of affront or possibly offense, only slightly false, but Twilight seemed to realize she was being spoken of. The sudden uptick in speed caused Celestia’s eyes to widen and her breath to stop short, her first (and at this rate certainly not last) climax of the evening... With somepony watching. There would most definitely be some kind of punishment arranged for this in time, but right now, Matte was just giving her a salacious grin and not budging.

“I... Well, yes, if you wish to put it that way. She made a rather lovely confession to me, and I accepted, earlier today. Yesterday’s visit was merely a well-timed fluke.”

“What is it with flounders and good timing?”

She deadpanned at him until the joke clicked in the back of her head, and she laughed out loud. It was an atrocious pun, but still, he seemed to have not caught on to her perverted predicament yet, so she could forgive bad humor.
“Mmmmh, I think it’s an issue of upbringing.”

“Oof, speakin’ a timing, I’ve got to dash- I’ll likely see ya later, neigh?”

“Of course.”

Matte Finish bowed and went to walk away, and she sighed with relief.
“Have a good evening, Princess! And you too, Ms. Sparkle.”

If she had not been in the grip of another orgasm, at least in part due to being caught, she was positive it would have been quiet enough to hear a pin drop.

--------

After a fair bit of clean-up, straightening of outfits and generation of alibis, they had begun the walk back to the ballroom. Celestia looked at her student with dawning worry, having realized something as they walked. It was a silly thought, but she had to confirm it.
“Twilight...”

“Mmh... Yes, Princess?”

She blushed, looking away from the younger mare. This was a rather odd question to spring, after all.
“Did I not... Did I fail to please you?”

Twilight spun around and turned to her, looking both confused and worried in equal measure.
“What!? No! I... you pleased me. A lot. Wow, did you ever... Hehe.”
She trailed off into blushing reminiscence.

“Oh. I simply, well, I worried- I barely noticed any reactions from you during that little... conversation.”

And at this Twilight blushed, stopping in her tracks and looking around to make sure nopony could hear her.
“Weell, see... You were pleasing me a lot, like I said, but I thought it would, um... be rude. To shout into your, uhm, rear. So I restrained myself.”

Inwardly, a sigh of relief. Outwardly, a brilliant smile with just a hint of what the various Equestrian tabloids (anonymously-authored, for the safety of said authors) had a tendency to call her ‘trollface’.
“Dear, you do not ever have to worry yourself about restraint. I believe my history has left me quite impossible to either offend or unsettle. So next time... Shout all you want.”
She finished with a wink, and for her part, Twilight simply blushed even more deeply, following her again- More closely now. Celestia whipped her tail over Twilight’s back, and pulled her close. The two of them, hip to hip, made their way back towards the Coterie. With any luck, the closing ceremonies would take mere minutes (the ballroom being nearly empty by now) and they could abscond to one bedroom or another to get rest... Or possibly more active forms of leisure.

It was shaping up to be a wonderful weekend, indeed.
